- Abstract
Seventy percent of the embryonic losses after synchronization out of breeding season in goats are originated due to luteal insufficiency. The aim of this study was to investigate the effects of administrations of GnRH or progesterone after mating on pregnancy rates during anestrus season. A total of 30 heads of Saanen goats were used during the anestrus season, with no infertility problems. The goats are randomly divided into 3 groups. Synchronization program was applied by using intravaginal device containing progesterone (CIDR®) in all groups and mated in bucks. In G1 (n = 10) no application was performed after mating. In G2 (n=10) buserelin injections were made on the 12th day after the last mating. In G3 (n = 10), CIDR® was applied for 5 days on 5th day after last mating. Blood samples were taken at 12th and 30th days after mating from all goats and 30th day pregnancy examinations were performed. There was no difference between the groups in terms of pregnancy rates (p> 0.05), when the progesterone values were examined in blood samples taken at 12th and 30th days in each group; no statistically significant difference was found in any group except G2. The progesterone values measured in G2 on the 30th day were statistically different from the values measured in G1 and G3 (p <0.01). In conclusion, post mating buserelin or intravaginal progesterone administration has no effect on pregnancy rates; however buserelin injections have significantly increased progesterone levels.
